程序执行成功但却没收到邮件，测试时在to里增加中文名会报错，但能收到邮件，却无主题和内容。

Answer 1

就是根据网上的写的，程序执行成功但没收到邮件。
不行的话给个支持smtp的邮箱吧，我也给分

Answer 2

找到问题了，163的smtp有问题
谁提供个注册14天以上的qq邮箱，我就把分给他

Answer 3

有點亂重發using System.Net.Mail;
using System.Net.Configuration;
public static bool SendEmails(string ClientEmal,string Subject,string Body,string CcEmail,string filePath)
        {
            MailAddress EmailFrom=new MailAddress("[email protected]");
            MailAddress EmailTo=new MailAddress(ClientEmal);
           
            MailMessage Email=new MailMessage(EmailFrom, EmailTo);
            Email.Priority= MailPriority.High;
            Email.IsBodyHtml=true;//设置邮件格式            Email.Subject= Subject;
            Email.Body= Body;//添加抄送电子邮件if(CcEmail!="")
                Email.CC.Add(CcEmail);if (filePath!="")
            {// Server.MapPath("EmailAttachment\\") + "Data.rar";//附件路径                Attachment data=new Attachment(filePath, System.Net.Mime.MediaTypeNames.Application.Octet);// Add time stamp information for the file.                System.Net.Mime.ContentDisposition disposition= data.ContentDisposition;
                disposition.CreationDate= System.IO.File.GetCreationTime(filePath);
                disposition.ModificationDate= System.IO.File.GetLastWriteTime(filePath);
                disposition.ReadDate= System.IO.File.GetLastAccessTime(filePath);// Add the file attachment to this e-mail message.                Email.Attachments.Add(data);
            }
         
            SmtpSection cfg= NetSectionGroup.GetSectionGroup(WebConfigurationManager.OpenWebConfiguration("~/web.config")).MailSettings.Smtp;
            SmtpClient Client=new SmtpClient(cfg.Network.Host);//验证 (Credentials 凭证)            Client.Credentials=new System.Net.NetworkCredential(cfg.Network.UserName, cfg.Network.Password);//处理待发的电子邮件的方法  (Delivery  发送,传输)            Client.DeliveryMethod= SmtpDeliveryMethod.Network;try
            {
                Client.Send(Email);returntrue;
            }catch (SmtpFailedRecipientsException ex)
            {for (int i=0; i < ex.InnerExceptions.Length; i++)
                {
                    SmtpStatusCode status= ex.InnerExceptions[i].StatusCode;if (status== SmtpStatusCode.MailboxBusy|| status== SmtpStatusCode.MailboxUnavailable)
                    {// Response.Write("Delivery failed - retrying in 5 seconds.");                        System.Threading.Thread.Sleep(5000);
                        Client.Send(Email);
                    }else
                    {                    }
                }            }returnfalse;
        }
WEB.CONFIG 配置 stmp ：
XML code
邮件配置
--> <system.net>
 <mailSettings>
 <smtpdeliveryMethod="Network" from="[email protected]">
 <networkhost="smtp.163.com"  userName="[email protected]" password="*****"/> </smtp> </mailSettings>
 </system.net>

Answer 4

catch (SmtpFailedRecipientsException ex)
            {for (int i=0; i < ex.InnerExceptions.Length; i++)
                {
                    SmtpStatusCode status= ex.InnerExceptions[i].StatusCode;if (status== SmtpStatusCode.MailboxBusy|| status== SmtpStatusCode.MailboxUnavailable)
                    {// Response.Write("Delivery failed - retrying in 5 seconds.");                        System.Threading.Thread.Sleep(5000);
                        Client.Send(Email);
                    }else
                    {                    }
                }这里解释下
